Products for civil engineering and road and railway construction were a passion of the company's founder, Leo Bermüller, as far back as 1960. In the course of the company's history, we have developed from a regional trading company to a pan-European specialist in modern construction products. Today, the company is run by Rudolf Bermüller, representing the second generation of Bermüllers and, with Stefan Bermüller, the next generation is already waiting in the wings to lead the company to further success in the future.

We offer a comprehensive range of geotextiles, such as non-woven fabrics and woven geotextiles, geotextile-related products such as geogrids, asphalt reinforcement grids, drainage mats, drainage grids, erosion control mats, geosynthetic clay liners, also known as bentonite mats, and sealing membranes, all of which belong to the category of geosynthetics.

BEGRID TG Geogrid

Bildunterschrift Beschreibung

The mode of action of the BEGRID TG Geogrid is simple and effective. Loads within the structure are distributed across a wide area by the geogrid before being transferred to the subsoil, thus avoiding any overloading caused by point loads. This avoids the need for costly and laborious earthworks, such as soil improvement measures or the replacement of soil with load-bearing material.

BEGRID TG Geogrids produce excellent results in terms of reinforcement. BEGRID TG is made from UV-resistant polypropylene (PP) membranes. In the production process, a predefined pattern of holes is punched into the membranes, which are then stretched laterally and longitudinally. This forms a dimensionally stable geogrid with low elongation.

The extremely robust and bending-resistant grid structures consist of monolithic ribs and intersection points. In contrast to other types of geogrid, no jointed nodes are formed during production. The geogrids are instead formed from a single piece of material. These typical product characteristics make BEGRID TG particularly well suited for use in civil engineering and road construction.

TERRAMESH Green

Design of TERRAMESH Green

The areas of application cover a broad spectrum, from traditional subgrade stabilisation through to noise barriers, embankments and wall structures.

One area that presents a special challenge with regard to slope stabilisation is the construction of extremely steep embankments and wall structures. The reinforcement must be designed to provide the structure with adequate stability, to ensure internal and external stability against collapse and to protect the exposed surface against erosion.

In the meantime, infrastructure elements also have to fulfil increasing expectations regarding their appearance and ecological compatibility, whilst also being financially viable. TERRAMESH system solutions, made of innovative steel wire elements, offer a reliable and economic alternative to traditional construction methods using concrete.

BEVENT SK Structured Separating Layer

BEVENT SK is a bond of a a three-layer vapour-permeable separating roof underlay membrane and a randomly arranged monofilament wire mat. The product is equipped with a self-adhesive butyl stripe.

BEVENT SK serves as a ventilation and spacer layer between the roof structure and the metal cladding. The open structure of the randomly arranged monofilament prevents the permanent accumulation of water, and the vapour-permeable roof underlay membrane provides the highest level of protection against the elements during the construction phase.

If you wish to protect insulation layers, flat-roof sealing membranes or waterproofing membranes of buildings against mechanical damage, then structural protection mats made of granulated rubber are the ideal product. These mats can also be used as a temporary protection layer for floors or stairs.

REGUM structural protection is available as mats or sheeting and can be laid quickly and easily. The material is permeable to water, weather-resistant, absolutely rotproof, and is able to support loads immediately after unrolling and laying.

Safety surfaces made of granulated rubber enable you to meet playground safety standards. They can also be used to excellent effect in outdoor areas in retirement homes, care centres, hospitals, leisure parks, swimming pools, shopping centres, hotels and gardens.

General information about BEBIT Asphalt Reinforcement Grids

General Information

Around 95 % of classified highways are constructed with an asphalt surfacing layer. The construction class and thus the road pavement design are selected according to the traffic loading. This ensures that a solution can be found that is tailored to the loading conditions and is both technically satisfactory and economically justifiable. The rapid increase in car and HGV traffic in recent years has led to increasing levels of road damage.

To combat these effects, “technical textiles” such as asphalt reinforcement grids have been successfully employed in road construction since the 1980s. In the meantime, a wealth of experience has been compiled in the form of technical recommendations for the use of asphalt inlays and in regulations such as the FGSV Working Paper No. 69. BEBIT is our product range that has been developed in line with these principles.

BEBIT G is a woven grid that has high tensile strength and is made of glass fibres with a melting point above 850 °C. The fibre bundles are encased in a bitumen coating.

Bildunterschrift Beschreibung

BEBIT G Asphalt Reinforcement Grids have an extremely high constrained modulus that allows the immediate absorption of high tensile forces with minimum elongation. This results in the concentration of stresses in the asphalt layer and the immediate activation of the reinforcement. The open structure of BEBIT grids ensures optimum bonding between the layers.

BEBIT G PLUS Asphalt Reinforcement Grids belong to the BEBIT G range and have an additional layer of mesh infill made of glass roving. This type of grid offers a real bonus with regard to functionality and ease of installation, without having to resort to dual-component materials.

Functionality of BEBIT Asphalt Reinforcement Grids

Functions

Reinforcement

BEBIT G Asphalt Reinforcement Grids are capable of absorbing the tensile forces in multi-layer asphalt constructions. This prevents or minimises the propagation of existing cracks (so-called reflection cracks) through to the overlying asphalt layer.

In this case, the term reinforcement means the absorption of tensile forces within the plane of the asphalt inlay. In contrast to the reinforcement of unbound sub-base layers, the asphalt reinforcement is not placed in the tension zone of the road pavement and therefore does not perform the task of dissipating the stresses caused by traffic loading as its primary function.

Its function is to restrict the movement of crack boundaries or joint edges in the interface between the base layer and the overlying asphalt layer.

Bildunterschrift Beschreibung

When bonded correctly, the reinforcement prevents the cracks from opening. The reinforced system thus has an improved load-bearing capacity and its useful life is significantly increased in comparison to systems with no reinforcement.

The extended functions of BEBIG G PLUS offer decisive advantages during installation. In combination with a suitable bitumen emulsion, the closed structure of the grid created by the glass roving improves the bond with the subsurface during laying.

Asphalt reinforcement materials are also used in situations where asphalt layers are subject to extreme fluctuations in temperature, since these conditions are liable to promote crack formation. Asphalt sealing systems in water engineering, landfill sites and agricultural silo systems are thus also suitable fields of application for BEBIT Asphalt Reinforcement Grids.

BEBIT G Asphalt Reinforcement Grids are available in different strength categories ranging from 50 kN/m to 200 kN/m. The choice of strength category depends on the type of application, the type of damage, and the traffic loading.

Several factors play a decisive role in the selection of BEBIT G Asphalt Reinforcement Grids. These factors include:

Variables and constraints

The type of use of the traffic surface and the type and extent of any existing damage

Installation of BEBIT Asphalt Reinforcement Grids

Installation of BEBIT Asphalt Reinforcement Grids

Before installation can begin, the surface on which the grids are to be laid must be checked to ensure adequate evenness and must be also be cleaned. If any cracks, joints or other holes become visible, these must be sealed.

Immediately before laying the asphalt reinforcement, the clean, dry subsurface must be sprayed with a polymer-modified bitumen emulsion of grade C60BP1-S in accordance with TL BE StB 07. The subsurface temperature should not be less than 5 °C and the air temperature must be at least 10 °C during laying.

BEBIT asphalt inlays must be laid into the bitumen emulsion layer after the emulsion has broken. They must be laid in dry weather only and without creasing.

A road surfacing layer of at least 40 mm must be laid on top of the asphalt inlay immediately after the bitumen emulsion has dried.

BEBIT Asphalt Reinforcement Grids

After resurfacing the road, there is a risk that these existing cracks
can also propagate through the new asphalt surfacing layer within a
short space of time. BEBIT asphalt reinforcement grids have been
used successfully for many years to prevent the development of these
so-called reflection cracks. They are laid as a reinforcing layer
between the original pavement and the new surfacing.
